Boost Works hits 257 in the mile with their 2300+ horsepower S550 GT Coyote

The baddest S550 Mustang around? That would be this Boost Works example with a 2300+ horsepower Coyote under the hood. They did not build it to race dynographs but for the Texas mile where it recently went 256.9 miles per hour.

We rounded up to 257, big deal.

As for what is done to it obviously it has a built Coyote with a ton of boost from turbochargers.

They did not share too many details other than what it hit in the mile and a teaser video below.

This is the world's fastest S550 in the standing mile and that record isn't falling any time soon.
